[C320-list] Peel Away

[Allan S. Field]

According to what Gerry Douglas told me several years ago, the Catalina's
that have been laid-up with vinylester will not blister.  Further, the
vinylester is from rubrail to rubrail.  He specifically cited the boats in
CA that never come out for the winter as evidence of the need not to haulout
every winter.  In fact, I am not sure that any of the boats in southern CA,
such as Marina del Rey, ever come out except for bottom paint jobs.  When I
purchased Sea Shadow new 8 years ago, the dealer specifically told me that
putting a barrier coat on the bottom would void the Catalina hull warranty.
(This was the same dealer that neglected to remove the wax from the hull
before putting bottom paint on, resulting in 5 years of peeling paint before
I finally figured it out and had the hull peeled down and started over
again.  But that, and his failure to stand behind the problem, is another
story!)

That said, there were a series of C320 boats in the 300-400 range that had
blister problems.  Several were apparently "fixed"; I know of at least one
from that series where the blisters have come back.

The point is that I have been convinced that winter haulout and barrier
coating are unnecessary for Sea Shadow.  I now haulout every 2 years to
paint the bottom and otherwise leave her in the water all winter with a
bubbler running on a temp sensor and timer.

DISCLAIMER: I am not advising anyone else to do what I am doing.  Rather, I
am just passing along what "works" for me.  I would advise others however to
do thorough research for themselves.  And share with the rest of us your
results, especially if they deviate substantially from my research!

Barrier coat is an insurance policy against future blisters. And I might
add, it should not be put 
over blisters which should be dried out and possibly repaired if bad enough.
I've barrier
coated one boat that had blisters, but let it dry out all winter, without
any other repair because
they were small and sanding opened all of them. No further blistering
occurred. I've also
barrier coated two other boats that did not have blisters. One was two years
old, the other
new. With todays manufacturing, barrier coating may or may not be needed. My
current
320 does not have a barrier coat and it is 10 years old. It may never get
blisters. But it has
spent every winter out of the water -- I think this helps a boat to dry out,
thereby preventing
blisters????

If the boat has no blisters & this product doesn't damage the gel coat, is
it necessary to barrier coat?

I see they have newer products, some don't require the paper -- but I'd
suggest 
sing the 
ne that needs paper just to keep it in tact. Check it out.
Maybe buy one gallon, give it shot just to see for yourself.

ubject: [C320-list] bottom paint
My two cents. If a bottom is properly prepared each time, I think it can go 
ndefinitely without
and blasting or any other type of removal -- especially if ablative paint is

sed. (unless of course
ou race)  I haven't stripped a bottom for some time, but when I did I bought
a 
roduct from
ome Depot called Peel Away. (It was half the price over West Marine. I
notice 
est Marine sells Ready-Strip and Aqua-Strip which may be the same product
now. 
he product was put on with a trowel that has teeth and then a special paper
was 
ut over the
aint remover. In the case of my first use it took off 10 years of Petitt
hard 
ottom paint. Put it
n, went home for the night and came back the next morning with a four inch 
utty knife. Of course
put down plastic first, rolled it up for the trash -- done. Sanded the
bottom 
nd put on five coats
f Interprotect 2000/2001 then two coats of bottom paint. If you do this,
make 
ertain the first
oat of bottom paint goes on before the last coat of Interprotect has cured.
You 
ant the two to
eld together. If I was going to strip a boat I'd use the same process, it
has 
orked for me three
imes -- it doesn't touch gel coat or barrier coat and probably would not
work 
n epoxy paints.
Peel Away came in five gallons or one gallon containers. A great product.
You 
an probably do a search for paint removers and come up with something. Maybe

ven search on Peel Away.
Best of luck.

I left out some details in the initial posting for the sake of brevity, so
ere goes.  This is hull number 500.  I bought her about a year ago.  I've
ad the boat on a hydro-hoist and power washed the bottom, and to my
ntrained eye, there were no noticeable blisters.  This yard will not
epaint until the hull dries out, so the boat may be on stands for months.
hey would probably let me do some work myself if I were so inclined.  I
uess that once they start removing the paint, they'll be able to tell what
ondition the barrier coat is in.  This is all new to me, and like I said, I
on't have any real options on who can do the work here.

hris,
  I have always been against any sandblasting of the
ottom ----UNLESS----it is to a small blister area that needs removing.  If
ou have any blisters, they may need to dry out for several days before any
epairs are done.  The original bottom barrier coat (to prevent blisters)
ould be damaged with sandblasting. 
  You did not mention the hull number, but the blister protection method
sed by Catalina has changed over the years.  I had three small blisters on
y hull #219 in year number three (1997)---factory warrantee assistance was
ore expensive than me doing it myself and no futher problems have occurred.
  Other than the sand blasting part, the yard's approach seems
easonable--12 years is a long time for the original bottom paint.

'm about to have the first bottom job done on my 12 year old, freshwater
oat.  Without much in the way of available options on who will do the work
nd how it will be done, I really just need to decide whether the estimate
hat I've received is reasonable.  The yard will haul it out, sand blast the
ottom, then pressure wash the bottom and hull sides, prime the bottom with
light coat of bottom paint, then go back with two heavy coats of
nti-fouling bottom paint, and then apply a third coat along the water line.
hey use Petit Un-epoxy Plus bottom paint.  Any blisters would be dealt with
eparately.
Is there anything about this approach that seems wrong?
Thanks,
Chris Descher
